Introduction: Reviewing the reasons for return visits within 24 hours is a very important method of determining possible problems of emergency health care. Several causes stay behind unscheduled emergency return visits. Therefore, identifying these factors is crucial to set strategies in order to decrease the number of unnecessary visits.

Aim: To define the characteristics of the patients returning to the Paediatric Emergency Department (PED) within 24 hours via determining rate, number and demographic data of patients.

Materials and Methods: The present study design involves retrospective data collection of patients who returned to PED within 24 hours after being discharged. Data was included over six year period and was collected from July 1, 2010 to June 30, 2016. The data was analysed with SPSS17.0 statistical package for windows.

Results: A total of 1994 patients returned to PED within 24 hours from July 1, 2010 to June 30, 2016. The most common group of revisiting patients were toddlers (aged 0-2-year old), n=1168 (58.5%), and the least number represented young adolescents (aged 15-18-year old), n=82 (4.1%). Number of patients returning to PED in 24 hours has significantly increased within years from approximately 90 patients to 720 (p<0.05). This increase in number was observed in all and each age group (from 0-18 years of age) without any exception. Seasonal distribution of the patients showed no significant difference (p>0.05) for each age, but again, presented definite negative correlation with age (the older is the patient group, the less is the number of revisits). The most common time for revisits was 17-24 hours after first discharge from PED, n=1277 (64.04%).

Conclusion: The number of return visits is increasing over the years. The younger the patient is, more likely is the risk of unscheduled revisit to PED. Most of the patients returned to PED in 17 to 24 hours after discharge.
